Autumn 1

Place Value

Children have already represented numbers to 100 in Year 2. This unit provides the opportunity to revisit and consolidate their learning before moving on to numbers beyond 100. The main focus of this step is to ensure that children get a sense of the size of numbers to 100 and can see clearly the number of tens and ones each number is made up of. Children should be confident using a range of manipulatives, such as straws, a bead string and base 10, alongside their own drawings and jottings. Place value counters are not used in this particular small step, as they do not show the relative sizes of numbers, and children cannot see that 1 ten is made up of 10 ones

Addition and Subtraction

In Year 2, children learnt to add and subtract two 2-digit numbers, including with exchanges. In this unit, children build on that knowledge, working towards adding and subtracting 2-digit and 3-digit numbers with exchanges. To be successful with this, it is essential that children are confident in both using and applying their number bonds to and within 10 and this small step provides opportunity to consolidate this.
By the end of this small step, children should be more confident at recalling all the number bonds up to 10 in a variety of contexts. They will then apply this knowledge to number bonds to 100, for example: 3 + 2 = 5, so 30 + 20 = 50. Children use a variety of representations, including base 10, place value counters, double-sided counters, number lines, part-whole models and bar models.
